The following goof was marked as incorrect: "The soldiers from 2051 come from a time when 99.99% of the human population is dead and the war is nearly lost. Nevertheless, the governments from the present devote tremendous resources to sending millions of drafted civilians to 2051 to die almost certain deaths. There is no discussion of using the knowledge from the future to fight the impending war differently and prevent human extinction. Only at the end does it seem to occur to anyone to send the toxin back in time to change the future." Reason for it being incorrect was said to be: "However, it is possible to develop the toxin only with a female specimen available, i.e. in the future, and it cannot be possible to bring her back in the present for studies." Still, this does not explain why no effort was taken in 2022 to use knowledge from 2051 to alter the course of history.
